Стоит ли хранить изображения base64 в БД?

use Symfony\Component\DomCrawler\Crawler;
use Illuminate\Support\Facades\Storage;
use Illuminate\Http\File;

$desc = $request->input('some_html'); // POST with html
$dom_desc = new Crawler($desc);
$images = $dom_desc->filterXPath('//img')->extract(array('src')); // extract images
 
foreach ($images as $key => $value) {
    if (strpos($value, 'base64') !== false) { // leave alone not base64 images
        $data = explode(',', $value); // split image mime and body
        $tmp_file = tempnam('/tmp', 'items'); // create tmp file path
        file_put_contents($tmp_file, base64_decode($data[1])); // fill temp file with image
        $path = Storage::putFile('public/items', new File($tmp_file)); // put file to final destination
        $desc = str_replace($value, $path, $desc); // replace src of converted file to fs path
        unlink($tmp_file); // delete temp file
    }
